WILLIAMS CONTROLS part description

The WM81 series consists of non-grounded switches that respond to a drop of air pressure below a preset level. The WM81 switches feature an adjustment that allows the actuation setting to be modified. The switches are shipped from the factory with this setting pre-adjusted to 50-60 PSI (344, 7-413, 7 kPa). When the pressure drops below the preset value, these switches activate a light or buzzer to indicate that a low pressure condition exists. Part Number: 111237 Manufactured by Williams Controls.
