Switch Configuration
Driving the Switch
DC power connection
•
Connect pin 1 to supply (+20 VDC to +32 VDC)
•
Connect pin 15 to chassis ground to enable the electronic
position indicating circuitry and drive logic circuitry.
N O T E
Pin 15 must always be connected to ground to enable the electronic
position-indicating circuitry and drive logic circuitry.
C A U T I O N
If pin 15 is not connected to power supply ground, catastrophic failure will
occur.
N O T E
After the RF path is switched and latched, the drive current is interrupted by the
electronic position-sensing circuitry. Pulsed control is not necessary, but if
implemented, the pulse width must be 15 ms minimum to ensure the switch is
fully latched.
