94- Colombian Collar Bomb 3 – Switch
$23.95 – $73.95
This circuit is like the Colombian Collar Bomb 1, except that there are three switches and a place to use/not use an arm LED (LED1) with no pull-down resistor.
This circuit is like the collapsing circuit, except we have included a trap switch (SW1/SW2/SW3) to use as a victim operated switch. The circuit is essentially two circuits. The control circuit consists of the battery (B2), a diode (D1), the relay coil (RY1) and R1. The firing circuit consists of the switch side of the relay, the firing battery (B1), the two detonators which are in parallel with each other, LED1 and the pull-down resistor (R1). All of that is in series to the safe and arm switch (SW1).
