D2RW01L2

Snap action, limit switches are widely used in many industrial applications for a wide range of tasks, from providing basic feedback to measuring and recording system conditions. D2RW01L2 series limit switch is an example of such a product. It is intended to be used in low voltage DC and AC circuits.

The D2RW01L2 switching system can be used in commercial and industrial applications, and it is suitable for both on and off-delay switching, as well as momentary and latching. The latching feature allows the switch to be set to either "on" or "off" position, regardless of how the switch was originally set. The contact type is a snap-action bimetal, and the contacts are rated for 12A at 125/250VAC50/60Hz and 0.5A DC/AC.

The mechanical design of this switch is elegant and reliable, and enables its usage in a wide range of applications. It consists of an actuator with a plunger and an internal lever, a snap-action bimetallic contact and a plastic shell for environmental protection. An adjustable cam of small mass and an adjustable screw are integrated into the lever so that it can move or pivot on this lever when the actuator plunger is pressed.

The working principle of the D2RW01L2 limit switch is based on the snap-action of the bimetal strip, which physically exerts the force to move the contact of the switch. The bimetal strip is composed of two metals that have different coefficients of thermal expansion. When the temperature rises, the strip bends and reverses its shape when the temperature drops.

Upon pressing the actuator plunger, the cam, which is mounted to the lever, compresses the bimetallic strip and moves the leaver to the limit positions. The bimetallic strip then returns to its original shape and releases the contact, thus cutting or restoring the current flow. This switch can be used in a number of low voltage applications, including light switches, household appliances, and industrial machines.

In summary, the D2RW01L2 limit switch is a reliable device and offers flexible design that enables its use in a broad range of low voltage applications. Its snap-action switch provides quick and reliable switching action that is suitable for both on and off-delay switching.
