Large Spade Relay Bypass Switch.

Key Features:

• Spade Terminals: The image clearly shows large spade terminals (also known as blade terminals) protruding from the back of the switch. These terminals are designed for quick and easy push-on connections.
• Large Size: The term "large" suggests that this switch is designed to handle higher current loads compared to smaller switches.
• Bypass Switch: A bypass switch is typically used to temporarily override or bypass a circuit. This could be for testing, troubleshooting, or providing an alternate path for current flow.
• Plastic Housing: The switch appears to be encased in a black plastic housing, which provides insulation and protection.
• Terminal Markings: The numbers "85," "86," "87," and "98" are visible near the terminals. These are standard markings for automotive relays and switches, indicating specific functions within the circuit.
• Single Throw Contact: Based on the terminal configuration, it's likely a single throw switch, meaning it has one set of contacts that either connect or disconnect the circuit.
