A sensor ( ) for increasing signal time employs a resiliently deflectable member n( ) with a pressure sensitive signal element ( ) and base member ( ). The dampening effect of the elastic material provides a longer signal response time that allows sufficient time for a system to react without a need for additional signal conditioning circuitry. Sensor ( ) senses a selected path of movement for a moveable element ( ) and establishes a signal indicative thereof. The limit sensor includes a resiliently deflectable member ( ) for activating the signal at a predetermined station along the preselected path of movement and includes a base member ( ) for supporting the resiliently deflectable member ( ) and the pressure sensitive signal element ( ). An actuator ( ) receives the force (F) from the moveable element ( ) and transfers the force (F) to the pressure sensitive signal element ( ). In the preferred embodiment, the resiliently deflectable member ( ) includes a leaf spring ( ) positioned between the actuator ( ) and the pressure sensitive signal element ( ).

Sensor for increasing signal response time

A rotary transformer having a stator and rotor each formed by winding a coil on a non-magnetic bobbin and overmolding the bobbin and coil with magnetically permeable particulate material dispersed in a non-magnetic medium preferably selected from the group consisting of thermoplastic, thermosetting plastic and thermoplastic elastomer.

Rotary inductive coupling

A capacitive switch assembly includes an elastomeric sheet actuator for elastically supporting a switching member above a capacitive element comprised of a pair of conductive plates and a dielectric sheet. The elastomeric sheet supports the switching member so that upon user actuation to compress the elastomeric sheet, the switching member is directed to engage the capacitive element and selectively compress to effectively form a variable capacitor. Resilient deformation of the switching member can further vary the capacitance of the capacitor in an electrically detectable manner.
