SHL
Molded Terminal Models
Operation Indicator-equipped Models
The molded terminal model may be equipped with an operation indicator (neon lamp or LED) upon request to facilitate maintenance and
inspection.
The operation indicator is designed to illuminate when the Switch is not operating. (Because of the molded terminal model, any change
to the Switch wiring cannot be made.)
Note: Refer to the previous table for model numbers for Switch with molded terminals and operation indicators.
For AC
• The applicable voltage is 90 to 250 VAC (microload models: 90 to
125 VAC).
• Operating characteristics are the same as the basic model from
which the operation indicator equipped model is fabricated.
• Dimension are the same as the standard model.
Example:
Basic type: SHL-Q2255-MR
When placing your order for the molded terminal model with an neon
lamp operation indicator, specify the model number as SHL-Q2255-
LMR.
For DC
• LED indicator is provided.
• As a rectifier stack is incorporated, into the unit and no directionality
exists for connection of + and −, this type can also be operated on
AC.
• The voltage specifications are given below.
• Voltage ratings of LED indicators are as shown in the table below.
Example:
Basic type: SHL-Q2255-MR
When placing your order for the molded terminal with an LED
indicator rated at 12 V, specify the model number as SHL-Q2255-
L2MR.
Use of the molded terminal model is
recommended in locations subject to
excessive dust, oil drips, or moisture.
All types of SHL Switches can be fabricated
into a molded terminal version. In this case,
the molded terminal model will have the
same dimensions and operating
characteristics as the basic model from
which the molded terminal model is
fabricated.
