A pair of elongated movable contact members commonly secured to the bands between the adjacent portions thereof. The contact members project toward the proximal end wall of the sensor recess and are provided with flared proximal free end portions. The angularly related walls of a generally V shaped fixed contact project from the distal end wall of the sensor recess and are engaged by the movable contact members at actuated position. The end portions of the movable contact members laterally expand and the walls of the fixed contact laterally contract to absorb the energy of the moving mass of the sensor and eliminate contact bounce while maintaining electrical contact between the contact members to close an electrical control circuit. The distal end portions of the contact members may engage the distal end wall of the housing or an adjustable set screw to locate the roller bands and movable contact members in preload or unactuated position.
