Magnetic Release Unit Lascells (Each)

The simplest approach yet to this basic experiment in mechanics. By squeezing
the 'ears' of the release unit the ball bearing is released and the circuit
connections to a timer are broken at the same instant. The base unit is a
sensitive microswitch 'trapdoor' giving either make or break contacts at the
moment of impact. No power supplies are required, just a sensitive timer with
any START and STOP triggering. Manufactured in acrylic to modern design
standards with a rubber impact plate. Base dimensions: 150 x 130 x 30mm
Connections by 4mm leads **Alternative Magnetic Release Unit** Designed for
use with either 'g' by Free Fall Systems or the Monkey and Hunter apparatus.
The unit requires a low voltage, smoothed DC power supply at 4-6V and 0.5A.
Supplied with 4mm sockets and an aluminium handle for use with a standard
laboratory clamp stand. Dimensions: 40 x 40 x 35mm, excluding 200mm handle
Mass: 0.2kg **NB:** Retort stand and clamps are not included
