Abstract

An electrical miniswithch comprising a case including a case part forming a base having several electrical terminals extending therefrom, and a case part forming a cover, an instantaneous switching mechanism located in the case and comprising a flexible conducting blade subjected to a substantial pre-stress, and a push-button mounted sliding through the part of the case forming the cover to actuate the instantaneous mechanism. The miniswitch also comprises a compression spring opposing sliding of the push-button so that in the break position of the miniswitch the flexible conducting blade is biased by th push-button and the spring, retained by a stop on the push-button, and in the switched or make position of the miniswitch the conducting blade is not subjected to constraint from the push-button and the compression spring.

Claims6

Dependent claims

An electrical miniswitch having a break position and a make position, comprising:

a case comprising a cover and a base,
a plurality of electrical terminals extending from the base,
a first electrical contact and a second electrical contact both located within the case;
a high-speed breaking mechanism located within the case and comprising a flexible conducting blade comprising a tongue,
a push-button comprising a stop mechanism, and
a compression spring,
wherein the flexible conducting blade is pre-stressed biasing it towards the first electrical contact, and the push-button is mounted to slide through the cover to actuate the high-speed breaking mechanism, the compression spring opposing sliding of the push-button, such that when the miniswitch is in the break position, the push-button stop mechanism exerts a transverse force on the flexible conducting blade permitting the pre-stressed flexible conducting blade to contact the first electrical contact, and when the push-button is in the make position, the stop does not exert force on the flexible conducting blade, permitting the biased flexible conducting blade to contact the second electrical contact.
