1. Apparatus for providing a switch mechanism, comprising:
a housing containing within:
a pressure sensitive device comprising a resistive pressure sensor responsive to an applied force, said pressure sensitive device being mounted to said housing;
a first actuator moveably connected to said housing to enable said first actuator to move along an axis towards and away from said pressure sensitive device, so as to transmit said applied force to said pressure sensitive device; and
a first resilient member having a first end connected to said first actuator and a second end connected to said pressure sensitive device, wherein
said housing comprises a groove configured to receive said pressure sensitive device such that said pressure sensitive device is positioned accurately in manufacture; and
said pressure sensitive device comprises a positioning structure configured to receive said first resilient member so as to retain said first resilient member to said pressure sensitive device;
a guide rod attached to said housing, said guide rod being positioned perpendicular to a pressure surface of said pressure sensitive device; and
a second resilient member sleeved on said guide rod.
