Switch mechanism.

摘要

A switch mechanism is described in which a first contact carrier (12) having a first contact member (15), is movable between an inoperative position and an operative position. A latch mechanism (16, 25) retains the first contact carrier (12) in the operative position when moved thereto but a spring (14) urges the first contact carrier (12) towards the inoperative position. A second contact carrier (17) having a second contact member (23) and movable between first and second positions is biased by a spring (18) towards the first position where the first contact carrier (12) engages an abutment (21) on the second carrier (17). Movement of the second carrier (17) towards the second (lower) position causes the first carrier (12) to be moved into its operative position and the subsequent return of the second carrier (17) towards the first position is accompanied by the engagement of the first and second contact members (15, 23).
