Power Tap Switches

Material

Body: Ceramic, arc-proof

(models 212, 312, 412, 608).

Compression Molded Polyester

(model 111). Melamine Phenolic

(model 711)

High-current, Non-shorting Type

Model 711

Contacts: Silver alloy. Common

contact is rounded for assured

seating. Self-cleaning with built

in wiping action.

Terminals: Soldering. 711 also

accepts quick connectors; 412,

#10 screws; 608, 0.25” bolts.

Mounting

Model 711: Using ³/8-32 bushing

for ¹/8” thick maximum panel.

Four non-turn lug positions are

possible on the single, unen-

closed switch. Recesses in body

of switch permit positioning of

non-turn washer at “12, 3, 6 and

9 o’clock.” ³/16 “ hole for non-turn

washer. Shaft ¹/4”

NOTE: Since all tap switches are

electro-mechanical devices, they

are subject to wear and, there-

fore, have a finite life.

• Ceramic and metal construction

provides resistance to arcing,

burning and charring.

• Tandem assemblies available as

standard models.

• UL listed for models 111, 212,

312 and 412

• RoHS compliant product avail-

able Jan. 2006 Add “E” suffix to

part number to specify.

Switch, rated at 7 amps, has

Ohmite power Tap Switches

(high power rotary switches)

are constructed to provide

dependable, convenient

operation.

All Ohmite tap switches,

from 15 to 100 amps, have

ceramic arc-proof bodies and

metal alloy contacts. Their

all-soldered and all-riveted

construction assures mechani-

cal and operational integrity.

Even the smallest Ohmite Tap

a reinforced non-metal body

and solid metal alloy contacts.

These units feature high cur-

rent handling capability in a

small package.

F E A T U R E S

• “Slow-breaking, Quick-make”

action proved best for switching

AC current.

• Non-shorting type disconnects

previous circuit before establish-

ing contact for succeeding tap.
