Abstract
A switching device comprising a rubber switch, an operating member displaceable between at least two operative positions and a neutral position, and a cooperating member shiftable between the at least two cooperative positions and neutral position in response to displacement of the operating member. The operating member and the cooperating member are held in their neutral position due to the resilience of the rubber switch, while one contact is brought into engagement with a corresponding conductive element in the rubber switch when the corresponding cooperating member is shifted to one of the cooperative positions in response to the displacement of the operating member against the resilience of the rubber switch.
