Abstract
In a security system, a transmitter housing and first and second transmitter actuation elements cooperate to define thumb and finger saddles on opposite sides of the housing. The peripheral edge of the housing and the first and second actuation elements have matched configurations aligned at the thumb and finger saddles for guiding a hand to properly operate the transmitter while blocking other objects from accidental operation. The housing extends beyond the actuation elements at the ends of the elements while the actuation elements extend beyond the housing at the center of the elements. The housing has a first texture, such as a rigid plastic, while the actuation elements have a softer feel provided, for example, by an elastomeric material.
