Abstract
To permit direct attachment of a deceleration sensing element to a printed circuit board or the like, a housing (2) made of insulating material retains therein a flexing or bending piezo-ceramic transducer (4) which is electrically connected to terminals (5) passing through the housing, spaced by standard printed circuit board hole spacings from each other; electrical connection between the piezo-ceramic flexing or bending transducer (4) and the terminals (5) is obtained by an electrically conductive adhesive (6) filled into chambers formed in the housing and extending from both sides of the flexing or bending transducer. The housing is preferably encapsulated by a coating of silicone rubber, and can be inserted into a groove (9) in a support side wall (1) by an externally projecting winged spring (10), and secured therein by an adhesive (8).
