A portable radio which offers channel selection option requires some type of selector switch to facilitate access. The selector switch shown (Figure 1) serves the purpose mechanically. This switch consists of: (i) contact finger (ii) return spring (iii) slider (iv) housing These four components form a selector switch by snapping the contact linger, return finger and slider into the housing. To use this switch, a printed circuit board with three contact pads and four snapin holes are needed When the switch is snapped into the printed circuit board, the contact fmger will connect pad #l and pad #2 (Figure 2). If an external actuation is applied to slider, the slider will shift further towards the housing and elon- gate the contact finger. T+s, connection between pad #1 and pad #3 is closed! (Figure 3) and connection between pad #I and pad #2 is opened. When the actua- tion force is released, the slider will return to its original position, and the connection between pad #l and pad #2 is closed again.
