Abstract
A switch comprises a housing having an upper member and a lower member, an actuator disposed in the housing and rockably supported on the upper member, switch means for connecting and disconnecting a movable contact with a stationary contact when the actuator rocks on the upper portion, and a connecting terminal for an external electric wire electrically connected to the switch means. The switch means includes a movable contact element having the movable contact and a support element which rockably supports the movable contact element. At least one of portions contacting each other between the support element and the movable contact element is provided with a clad layer of a high conductive noble metal which extends in the rocking direction at the width less than that of the contacting portions.
Claims5
A switch comprising:
- a housing having an upper housing member and a lower housing member;
- an actuator disposed in said housing and rockably supported on said upper housing member;
- switch means responsive to said actuator for switching a movable contact in and out of contact with a stationary contact in accordance with rocking of the actuator;
- and
- a connecting terminal connected to said switch means and adapted to cooperate with an external electric wire;
- wherein said switch means comprises:
- a movable contact element having said movable contact disposed thereon, and
- support means for rockably supporting said movable contact element,
- wherein at least one of contacting portions of the movable contact elements and the support means which contact each other is provided with a clad layer of a highly conductive noble metal extending in a rocking direction of the actuator at a width less than that of the contacting portions;
- and
- wherein said support means includes a leaf spring comprising a connecting piece, legs extending downwardly from an end of said connecting piece, and a V-shaped piece connected to an upper portion of said legs, wherein said legs provide said V-shaped piece with elasticity.

- support means for rockably supporting said movable contact element,
- wherein at least one of contacting portions of the movable contact elements and the support means which contact each other is provided with a clad layer of a highly conductive noble metal extending in a rocking direction of the actuator at a width less than that of the contacting portions;
- wherein said support means includes a leaf spring comprising a connecting piece, legs extending downwardly from an end of said connecting piece, and a V-shaped piece connected to an upper portion of said legs, wherein said legs provide said V-shaped piece with elasticity;
- and
- wherein said leaf spring is bent into an M-shaped body to form legs at both sides of said V-shaped piece so as to provide said V-shaped piece with elasticity having a large value in the vertical direction but a small value in the rocking direction.
