Description

This Demonstration Bimetallic Strip consists of a
bimetallic strip fixed to a base, with a 12V halogen
bulb mounted below the strip. When the power
is switched on, the heat produced by the bulb
will heat the bimetallic strip causing it to bend
upwards, which breaks the circuit and the bulb
switches off. As the bimetallic strip cools down it
returns to its original shape, thereby completing
the circuit again, which switches the bulb back on
and the sequence repeats over and over until the
power is disconnected. A miniature version of this
concept is used in flashing bulbs and Christmas
lights.
Base dimensions: 130 x 80 x 30 mm.
