Abstract

1468672 Retractive switches PERADIN BONDED POLYMERS Ltd 6 May 1974 [4 May 1973] 21289/73 Heading H1N A switch for actuation by a vehicle comprises separate upper and lower portions 9, 13 moulded from rubber or synthetic plastics material with an elastically conductive member 31 bonded to a lower face of upper portion 9 and an elastically conductive member 23 bonded to an upper face of lower portion 13, portions 9 and 13 being joined together in a manner so as to prevent ingress of gas or moisture, with members 31, 23 in parallel spaced relationship, whereby when pressure is applied to the top of the switch, contact is made between members 31, 23 and broken when the pressure is released. The portions 9, 13 are stuck together with uncured rubber and then vulcanized. Member 31 may bridge two fixed contacts or several pairs of fixed contacts. The switch is intended for embedding in a roadway for operation by vehicles.
