Abstract

An electrical switch having an actuator 130, a contact station 112, and a base 110. The actuator 130 includes a movable portion 130f which moves translationally from a first position to a second position when a voltage is applied thereto and which returns back from the second position to the first position when the voltage is removed. The contact station 112 is provided in a center portion of the base 110 so as to fix contact portions 101s having stationary contacts 101a of stationary contactors 101. Movable contactors 103 each are made of a beam material and each have one end portion coupled with and fixed to a housing, and have another end portion provided with a movable contact 103a. An operational arm 105 has one end coupled with the movable portion 130f of the actuator 130, and the other end connected to the other end portions of the movable contactors 103.

Dependent claims

An electric switch characterized by comprising:

a housing;
a plurality of stationary contactors each including a stationary contact;
drive means received in the housing and including a movable portion which moves translationally from a first position to a second position when a voltage is applied thereto and which returns back from the second position to the first position when the voltage is removed;
a mount portion provided in the center portion of the housing so as to be protrusive and having a pillar for fixing contact portions having the stationary contacts of the stationary contactors;
a plurality of movable contactors electrically insulated from one another and each including a beam material having one end portion coupled with and fixed to the housing, and the other end portion provided with a movable contact electrically connected/disconnected to/from corresponding one of the stationary contacts;
and
an operating member having one end coupled with a movable portion of the drive means, and the other end connected to the other end portions of the movable contactors, wherein the operating member and the movable contactors form a substantially V shape.
