Abstract A switch assembly includes a manually operable push button, an elastic element, a rotatably mounted transmitter, and a microswitch, wherein the push button includes a pusher, which, upon actuation of the push button, exerts a first force on the elastic element, the elastic element connects to a force arm of the transmitter and is configured to transmit at least a part of the first force onto the force arm, and set the transmitter in a rotation, and the transmitter further includes a load arm configured to exert a second force on the microswitch during rotation of the transmitter. ## Claims ### Claim 1 A switch assembly comprising a manually operable push button, an elastic element, a rotatably mounted transmitter, and a microswitch, wherein the push button comprises a pusher, which, upon actuation of the push button, exerts a first force on the elastic element, the elastic element connects to a force arm of the transmitter and is configured to transmit at least a part of the first force onto the force arm, and set the transmitter in a rotation, and the transmitter further comprises a load arm configured to exert a second force on the microswitch during rotation of the transmitter, wherein an increase of the first force is compensated for through bending of the elastic element, and an increase of the second force is prevented through the bending of the elastic element when a stop of the microswitch is reached. ### Claim 2 (depends on 1) The switch assembly according to claim 1, wherein the microswitch is arranged laterally offset from the pusher of the push button. ### Claim 3 (depends on 1) The switch assembly according to claim 1, wherein the elastic element is configured as a spring plate. ### Claim 4 (depends on 1) The switch assembly according to claim 1, wherein the force arm and the load arm are arranged to be offset from one another on the transmitter. ### Claim 5 (depends on 4) The switch assembly according to claim 4, wherein the offset is 90°. ### Claim 6 (depends on 1) The switch assembly according to claim 1, wherein the load arm is bent in at least two different directions. ### Claim 7 (depends on 1) The switch assembly according to claim 1, wherein the elastic element is connected at a first end of the elastic element with an attaching element and at a second end of the elastic element with the force arm of the transmitter, and the pusher of the push button acts on the elastic element between the first and the second end. ### Claim 8 (depends on 1) The switch assembly according to claim 1, wherein the elastic element has a pretension in direction of the push button. ### Claim 9 (depends on 1) The switch assembly according to claim 1, further comprising a chassis of a computer system, wherein the switch assembly provides an on/off-switch mechanism for a computer system, and the push button is arranged on the chassis of the computer system. ### Claim 10 (depends on 1) The switch assembly according to claim 1, further comprising an LED light source and the load arm and the transmitter are configured as a light guide. ### Claim 11 (depends on 10) The switch assembly according to claim 10, wherein the push button comprises at least one light guide element and light emitted from the light source is transmitted onto the light guide element of the push button via the load arm, and illuminates the push button. ### Claim 12 (depends on 1) The switch assembly according to claim 1, wherein the pusher of the push button abuts the elastic element. ### Claim 13 (depends on 1) The switch assembly according to claim 1, wherein the pusher of the push button, upon actuation of the push button, acts on the elastic element. ### Claim 14 A switch assembly comprising a manually operable push button, an elastic element, a rotatably mounted transmitter, and a microswitch, wherein the push button comprises a pusher, which, upon actuation of the push button, exerts a first force on the elastic element, the elastic element abuts a force arm of the transmitter and is configured to transmit at least a part of the first force onto the force arm, and set the transmitter in a rotation, and the transmitter further comprises a load arm configured to exert a second force on the microswitch during rotation of the transmitter, wherein an increase of the first force is compensated for through bending of the elastic element, and an increase of the second force is prevented through the bending of the elastic element when a stop of the microswitch is reached. ### Claim 15 (depends on 14) The switch assembly according to claim 14, wherein the force arm and the load arm have a weight distribution such that a weight of the force arm and the load arm is arranged to move the transmitter back to its initial position after an actuation of the push button. ### Claim 16 (depends on 14) The switch assembly according to claim 14, wherein the pusher of the push button abuts the elastic element. ### Claim 17 (depends on 14) The switch assembly according to claim 14, wherein the pusher of the push button, upon actuation of the push button, acts on the elastic element.
