Reaction Time

Stick before dropping

Bell , Solenoid & Cam Assy.

The Dropping stick is made out of wood with SS etched scale fitted in a recess. The assembly slides on two corners in Teflon fitted slides . The timer Assy. is made with a one RPM motor with 3 positions cam . The positions are not uniform thus it is difficult to guess the next release time. The holding is done with a Solenoid latch . The solenoid releases the stick , strikes the Bell and Lights the Bulb.
