Control Switches
SJE-Rhombus control switches must be installed according to national and local electrical codes. SJE-Rhombus narrow angle control switches are used with control panels and alarms. For more infomation on control switches, please visit these products: SJE SignalMaster® |

Is the control panel or alarm off when the control switch is in the "on" position? (up for a normally open application or down for a normally closed application)
Is the control panel or alarm on when the control switch is in the "off" position? (down for a normally open application or up for a normally closed application) There may be a problem with the wiring, the control switch, or other panel components. Disconnect power before proceeding.
Control Panel/Alarm
Inspect the power cord for damage. Check the control panel/alarm installation instructions for correct wiring positions for power.
Control Switch
Make sure the float switch is the correct model for the application. A Normally Open (NO) float switch is used for high level alarm applications and Normally Closed (NC) float switch is used for low level alarm applications.
NOTE: On an SPDT switch, the black and white wires are used for a N/O switch and the red and white wires are used for a N/C switch.
Check the label on the float switch cable. If the cable label is gone:
- Raise the float up. If there is continuity through the switch, it is a normally open switch.
- Lower the float down. If there is continuity through the switch, it is a normally closed switch.
Check the control panel/alarm installation instructions for correct terminal positions. Check the connection between the float cable leads and the terminal strip. Check the float for proper positioning or obstructions which may have caused the float to hang-up. Inspect the float cable for damage.
To test for continuity:
Disconnect the float cable leads from the terminal strip. Connect a volt/ohm meter to the black and white float leads. Move the float to the "on" position (up for high level alarm models, down for low level alarm models). If the volt/ohm meter reads no continuity, return the switch to your supplier.
NOTE: On an SPDT switch, the black and white wires are used for a N/O switch and the red and white wires are used for a N/C switch.
Is there excessive sloshing or weight in the float?
Gently shake the float. If there is excessive sloshing, or if the float feels heavier than normal, there may be liquid in the float housing. If these conditions exist, return the float to your supplier.
NOTE: SJE’s mercury switches will have some sloshing sound due to the mercury in the switch. Mechanical switches utilize metal components that will cause some sound as well.
Was the switch used in an application other than those recommended in the product literature?
Gather information from the customer or installer and consult product literature.
