1,250,412. Electric switches. ESSEX INTERNATIONAL Inc. 30 Jan., 1969 [2 Feb., 1968], No. 5214/69. Heading H1N. [Also in Division G4] In vehicle signalling apparatus having an operator 7 for operating direction signals and an actuator 25 movable from an inoperative position (Fig. 1) to an operative position (Fig. 5) for operating both direction signal indicators simultaneously such as for hazard signals, cancelling means 48-50 is provided operable in response to operation of the operator 7 to return the actuator 25 to its inoperative position. By pushing in hazard warning switch 25 an abutment 48 and end 32 of the actuator 26 of this switch are moved from the position shown in Fig. 1 to that shown in Fig. 5. This also causes movement of a pin 45, which is secured to a switch carrier 35a, in a slot 43 formed in the actuator 26. Movement of the pin in the slot causes the carrier 35a to move to the right and connect movable and fixed contacts 39, 34 of the hazard switch. This connects an auxiliary flasher (F-2, Fig. 7, not shown), to flash all the direction signal lamps. The flasher (F-1) used for the turn signals is connected to the direction signal lamps by a direction signal switch 13 (G) which is operated via a pin-and-slot arrangement 15, 16 by the turn lever 10 and operator 7. The hazard switch actuator 26 is latched in the operative position by the pin 44 being located in a slot 46 due to the action of a spring 38. On moving the direction indicator switch lever 10 and operator 7 angularly to either of the turn positions or from one turn position to the neutral position, the pins 49, 50 attached to the operator 7 cause abutment 48 to return the hazard actuator 26 outwardly to the inoperative position shown in Fig. 1, where the contacts 39 and 34 disengage. Also the hazard actuator 2 may be returned to the inoperative position by rotation of the vehicle steering wheel shaft 4 which causes a cam 5 to abut the end 32 and return the actuator 26. Further, the hazard switch 25 may be also returned by pulling the knob 28. The direction indicator switch operator 7 is returned to the neutral position by the cam 5 abutting fingers 17 on rotation of the steering shaft 4. The Specification draws attention to Specification 991,720. |
