(54) | Switch mechanism |
(57) A switch mechanism is described in which a first contact carrier (12) having a first
contact member (15), is movable between an inoperative position (Figure 1) and an
operative position (Figure 3). A latch mechanism (16, 25) retains the first contact
carrier (12) in the operative position (Figure 3) 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 (Figure
1) 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). |
