TILT AND TIP-OVER SWITCHES
The tilt and
tip-over switches and motion sensors are available as mercury metal
and our patented non-mercury metal (patents #5.209.343 and
#5.332.876.). Mercury glass tilt switches are also available. All
switches are evacuated, filled with inert gas and hermetically
sealed to ensure long life and low contact resistance.
TILT SWITCHES
Tilt switches
are used to sense movement (tilt) of a device above and below a
horizontal axis. A typical use is in a thermostat. A glass mercury
switch is mounted to a bi-metallic spring which expands and
contracts with temperature. As the spring moves, the switch contacts
pass through the horizontal plane, opening or closing to operate the
furnace or boiler.
The angle
through which the switch must move for proper operation – the
differential angle – is measured from the point of just make to just
break; it is specified as a maximum. When selecting a tilt switch,
it is important to ensure that the operating mechanism can move the
switch through an angle greater than the differential angle.
Some additional
applications include: level controls, appliances, security alarm
systems, toys and games, float switches and water-treatment
equipment (non-mercury) .
TIP -OVER
SWITCHES
Tip-over switches
sense tilt over 360° of a vertical axis. A common use is in portable
heaters used in the home to prevent electrical shock or fire. When
the heater tilts more than a specified angle, the switch operates
turning the heater off. This angle, called the operating angle,
describes the angle from vertical to the point of contact operation,
subject to a tolerance, ie. 45° ± 10° (35° to 55°). Both normally
closed (tilt to open) and normally open (tilt to close) switches are
available.
Some additional applications include: portable lamps, PC anti-theft
devices, vending-machine alarms and machinery security systems
