Abstract

1520327 Retractive switches LABAVIASGE 17 June 1976 [17 June 1975] 25161/76 Heading H1N An electrical switching device for the control of a multi-stage braking system comprises a retractive push-rod 6 carrying a pin whose ends 10 engage in inclined slots 11 in a member 8 of plastics material, actuation of the pushrod sliding member 8 laterally in a plastics housing 3 to cause successive engagement of spring-loaded bridging contact bars 16a, 16b, 16c, 16d with fixed contacts 19, member 8 being mounted either as shown for actuation by depression of the push-rod or inverted for successive engagement of the contacts as the push-rod is released, movement of the push-rod being controlled by the brake pedal (not shown). In the embodiment shown the slots 11 do not penetrate to the exterior of member 8, but a hole 25 is provided on one side in the non- inclined end portion 24 of one of the slots 11 for insertion of the pin. In an alternative embodiment (Figs. 4, 5, not shown) the contact bars are replaced by thimbles (28) which actuate microswitches (26), the thimbles being in pairs facing outwardly with a common spring (29) between them, the microswitches at one end being such that the contacts are engaged as the operating plunger is released.
