Notes for Operation
・ SG-C1-21 series is a device used for enabling a machine (robot, etc.) when teaching the
machine in a hazardous area manually. Configure the enabling system so that the machine
can operate when the switch is in position 2 and an additional "start" is pushed to initiate the
operation.
・ In order to ensure safety of the control system, connect each pair of the contacts of the 3
position enabling switch (terminal No.NO1-C1 and NO2-C2) to a discrepancy detection circuit
such as a safety relay module. (ISO13849-1)
・ The base and the plastic part of rubber boot frame are made of glass-reinforced ABS/PBT.
The rubber boot is made of silicone rubber.
125V
250V
The screw is made of iron. When cleaning the SG-C1-21 series, use a detergent compatible

・ Turn off the power to the SG-C1-21 series before starting installation, removal, wiring,
maintenance, and inspection. Failure to turn power off may cause electrical shocks or fire hazard.
・ Do not disassemble or modify the switch. Also do not attempt to disable the grip switch
function, otherwise a breakdown or an accident will result.
・ When using the SG-C1-21 series for safety-related equipment in a control system, refer to the
safety standards and regulations in each country and region depending on the application
purpose of the actual machines and installations to make sure of correct operation.
Also, perform risk assessment to make sure of safety before starting operation.
・ Do not tie the grip switch around the button with a tape or string to keep the switch in position
2. Otherwise the original function of the switch is not utilized, posing a great risk of danger.
・ Please note that permanent installation of the grip switch at the machine is inadmissible.

Use contacts of terminal No.NO1-C1 and NO2-C2 for the output of enabling system.
The above operating characteristics illustrate the performance when the center of the
rubber boot is pressed. Pressing the edge activates one of the two 3 position enabling
switches inside earlier than the other, and may cause a delay in the operation of the
SG-C1-21 series.

Wiring Instruction
・Solder the terminal at 310 to 350ºC within 3 seconds using a 60W soldering iron. Sn-Ag-Cu
type is recommended when using leadfree solder.
・When soldering, do not touch the control unit with the soldering iron. Also ensure that no
tensile force is applied to the terminal. Do not bend the terminal or apply excessive force to
the terminal.
・Use non-corrosive rosin flux.
・Because the terminal spacing is narrow, use protective tubes or heat shrinkable tubes to avoid
burning of wire coating or short circuit.
・When using a stranded wire, make sure that adjoining terminals are not short-circuited with
protruding core wires.
・Use copper Wire 60/75 degree C only. (UL508)
・The wiring has to be installed according to GS-ET-22, 4.2.6.
