JouYang Electrical: speaker switch manufacturer and speaker switches design in China.

Established in 1990, China JouYang Electrical Products Co.,Ltd. is known as a leading speaker switch manufacturer and designer of high and low-voltage electric appliance in China. We integrate scientific research, development, production, sale and service in one company. Our custom speaker switches products are characterized by their superior dustproof, splash-proof, anticorrosion, fire-resistant, thermo-stability and aging-resistant properties. Having received ISO9001 certification for our manufacturing and sales systems, we have also been issued European 'CE' and Chinese 'CCC' safety authorizations for our products. All of our OEM speaker switch products are strictly according to IEC/GS/EMC/LICE/UL/CSA standard and guaranteed by People's insurance Corporation of China (PICC).

Connect up to 4 pairs of speakers to your stereo system for music throughout your home or office
Pairs can be played individually or in combination
Impedance protection allows a single amplifier to safely power several pairs of speakers
Designed for use with amplifiers up to 100 watts per channel
Accepts up to 14-gauge wire; supports speakers from 4 to 16 ohm impedance
Connect up to four pairs of speakers (eight individual speakers) to your stereo system for music throughout your home or office. Dual protection circuits shield the unit from overload, and automatic polyswitches turn it off when overload or excessive volume is detected, then reset it when the overload is removed or the volume is reduced. The SIMA SSW4 allows connection of 4 speaker pairs to a stereo system, for music throughout the home or office.

High current amplifier protection circuitry allows you to use up to 4 speaker pairs without damaging your amplifier.
High current resistors with aluminum finned heat sinks for maximum power delivery, up to 150 watts per channel.
High quality extruded aluminum chassis for heat dissipation.
Accepts any gauge speaker cable terminated with Monster Angled Gold Pin connectors.
24k gold contact spring-loaded connectors for maximum signal transfer and easy cable hookup.
Many people demand the flexibility and convenience of using multiple speakers throughout the house - even outdoors. If you hook up more than one speaker pair to your amplifier, however, the impedance (ohms) may drop to a dangerously low level, stressing your amp beyond its limits, causing circuitry damage or shutdown. You may avoid this potential nightmare by connecting your speakers to a multiple speaker selector. However, ordinary speaker selectors can also degrade system performance. Although they use a resistor "in series" to protect your amp from low impedance loads, these ordinary inductive resistors can cause noticeable high frequency loss, so you hear less detailed music reproduction. The power rating is often low, potentially damaging your speaker selector if you're using a high current amplifier.
