DACT CT3 Audio Selector Switches

Very compact audio selector switches that switch between sources. All contacts and connections are gold plated for long life even in the most challenging environments. Same basic construction and size as the DACT CT2 audio attenuators and CT4 balance controls. Can be used in all sorts of applications, projects, upgrades or manufacturing. Switch audio signals or other types of signals with this high precision, quality multi-position rotary switch.

DACT CT3 wire eyelets connections for wire.

DACT CT3 wire eyelets and pin connections.

Details:

CT3-6-2/wire
- 2-pole switch.
- Solder eyelets for wire connections.
- 6 positions.
- Non-shorting.
- Switches up to 2 non-balanced channels, signal only

Technical:

CT3 is a high quality Audio Selector Switch. It is based on the same high precision, Swiss made switching mechanism as the DACT CT2 audio attenuators. CT3 is a non-shorting type of switch making sure neither of the input sources will be short-circuiting each other when the switch is operated.

Features:

Gold plated contacts for long lifetime even in hot and humid environments
High reliability
Matches perfectly with DACT CT2 audio attenuators
Mechanically 'programmable' for 1 to 3 or 5 or 6 positions depending on version

Typical Applications:

Input selector in Do-It-Yourself Hi-fi / audio projects
Input selector switch in active or passive pre-amplifiers
Selector switch in professional audio equipment
Switch for long lifetime applications
Test equipment selector switch

Connections:

CT3-6-2, 6 positions, 2 poles:

ANTISTATIC CHARGES

To avoid noises from antistatic charges we suggest that one of the following two precautions is taken:

The DACT CT3 is mounted with electrical connection between its click-house and the equipment chassis.
A 1 MOhm resistor is connected between the CT3 click-house and equipment ground.
